A Dictionary of Music and Musicians/Art of Fugue, The
ART OF FUGUE, THE (Die Kunst der Fuge), a work of Sebastian Bach's, in which the art of fugue and counterpoint is taught, not by rules but in examples. It was written in 1749, the last year of his life, and is therefore the last legacy of his immense genius and experience. The work consists of sixteen fugues—or in Bach's language 'counterpoints'—and four canons, for one pianoforte, and two fugues for two pianofortes, all on one theme
in every variety of treatment; and closes with a fugue on three new subjects, in the same key as before, the third being the name of BACH (according to the German notation):—
This fugue leaves off on a chord of A, and is otherwise obviously unfinished, interrupted, according to Forkel, by the failure of Bach's eyes, and never resumed. On the other hand the writing of the autograph (Berlin Library), though small and cramp, is very clear, and not like the writing of a half-blind man. We learn on the same authority that it was the master's intention to wind up his work with a fugue on four subjects, to be reversed in all the four parts; of this however no trace exists. The Art of Fugue was partly engraved (on copper) before Bach's death, and was published by Marpurg in 1752 at four thalers, with the addition at the end of a Chorale, 'Wenn wir in hochsten Nothen sind,' in four parts in florid counterpoint, which is said to have been dictated by the master to his son-in-law Altnikol very shortly before his departure, and is thus his 'Nunc dimittis.' This chorale, which has no apparent connection with the preceding portion, is in G major; it is omitted in the editions of Nägeli and Peters, but will be found in Becker's 'J. S. Bach's vierstimmige Kirchengesänge' (Leipzig, 1843).
